Research on Mechanics System in Civil Engineering through Computer Big Data Technology and Visual Simulation

Metro section tunnels are constructed by undercutting method. Different section excavation methods and excavation sequences will cause different section deformation, vault subsidence and ground surface settlement. Therefore, how to excavate sections reasonably and what support methods are adopted, And the reinforcement measures of the surrounding rock masses will become the key factors for controlling surface settlement. Aiming at the characteristics of tight construction period, district filling of different materials, and high material transportation intensity in subway section tunnel construction, the functions and design principles of the subway section tunnel construction scheduling and simulation adopted, system are analyzed, and the construction information management and The design idea of optimizing the combination of deployment, information management and visualization technology, systematically discussed the main content and implementation methods of each function, and designed and developed practical software for related projects. Finally, the paper uses actual cases to carry out finite element numerical simulation calculations. A more reasonable excavation and support method is obtained through comparison and selection, which can be used as a reference for similar projects.
